NOVELTY - Preparing a fuel cell catalyst alloy comprises (i) preheating an inert gas and moistening, heat treating the carbon material in the moistened protective gas to perform a pore-forming reaction, rapidly cooling in a dry protective gas resulting in carbon material A with pore structure; (ii) heat treating carbon material A in an air atmosphere to regulate the oxygen functional groups, resulting in carbon material B; (iii) dispersing carbon material B to obtain a dispersion liquid C, introducing a transition metal salt solution to solution C, heating to form a carbon slurry, and heat treating in a protective gas to obtain a composite material D, (iv) introducing into a dispersion solution, introducing a platinum dispersion solution, stirring and heating to obtain a composite material F; and (v) heating composite material F under a hydrogen argon/nitrogen mixed gas, and heat treating in an inert gas to obtain a composite material G and dealloying in a nitric acid solution. USE - The method is useful for preparing alloy catalysts for fuel cells with enhanced carrier anchoring function. ADVANTAGE - The preparation method of alloy catalyst has enhanced carrier anchoring effect. The catalyst has good initial activity and particle durability. The preparation technology has a natural technique process, good consistency, and can be popularized for industrial applications. The unique sectional heat treatment process design can change the pore structure and chemical properties of the carbon carrier, obviously increasing the anchoring effect of the carbon carrier and the alloy particles, improving the binding force of the two and the hydrophilicity of the catalyst.
